One of the most frustrating things when trying to cut carbs is finding a satisfying stand-in for bread, buns, tortillas, pita, etc. Bread-less sandwiches? Totally ridiculous, right? The solution: use romaine, collards, purple cabbage, and butter lettuce as grain-free bread doubles. Whether you are looking to lose weight, stick to a Paleo or raw diet, or avoid gluten altogether, these easy-to-assemble leafy boats, wraps, and cups will deliver the goods from plate to mouth. (Plus, they're fiber- and nutrient-rich.)
